Flashlights are portable, battery-powered, devices used for illumination. Flashlights are typically designed for particular uses. Emergency flashlights, for home use, in case of black outs; or for cars, used in case of emergency stops in the dark. Camping flashlights often feature a longer range of light. Safety flashlights are generally brighter with longer battery life and may feature different flash patterns, which make them ideal for road emergency situations.
